Question

A car and a delivery truck both start from rest and travel at the same rate, 5 m/sec. The truck travels for 5 seconds, while the car travels for 10 seconds. What is the traveled distance of the car compared to the truck? * a. Half as much b. The same c. Twice as much d. Four times as much

Answer 1

c. Twice as much

Step-by-step explanation:

The distance covered by the truck and the truck can be found by the following equation:

`s = vt`

where,

s = distance covered

v = speed

t = time

FOR CAR:

`s_(car) = (5\ m/s)(10 s)\\s_(car) = 50\ m`

FOR TRUCK:

`s_(truck) = (5\ m/s)(5 s)\\s_(struck) = 25\ m`

Therefore,

`(s_(car))/(s_(truck)) = (50\ m)/(25\ m) \\s_(car) = 2s_(truck)`

The distance covered by the car is twice as much as the distance covered by the truck. So, he correct answer is:

c. Twice as much
