A motorboat leaves a harbour and travels at an average speed of 8 km/h toward a small island. , Step 2: Identify the given. as stream assists distance travelled in 30 minutes = [b+3]*1/2 =b/2+ 3/2 tot. These distance, rate and time problems will be revisited later on in this textbook where quadratic solutions are required to solve them. 1. distance = time into downstream speed + time into upstream speed = (speed-3) + 30/60 (speed+3) = (s-3) + (s+2)/2 distance = [2 (s-3)+ (s+3)]/2 User Input : Distance (in meters) and the time was taken (as three numbers: hours, minutes, seconds). He rode a total of 31 miles. . Two bike messengers, Jerry and Susan, ride in opposite directions. This means that the time spent travelling at 40 km/h was 0.5 h. Distance, time and rate problems have a few variations that mix the unknowns between distance, rate and time. Then choose the sentence that answer the questions being asked. Every month,, A:let's assume present height of Demonte is x cm, then C.They are Polynesian. The total trip took 1 hour. What is the average speed of the man for the whole journey? Where, d is the distance traveled; v is the velocity; t is the time taken to travel; The distance-traveled formula can be applied to calculate the distance of driving a car or swimming laps in a pool. Then, assuming the car is traveling at a constant rate of speed the equation would be: How do you write the variable expression for: a quotient of 2 and the sum of a number and 3 ?
