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

Answer:

c. Twice as much

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,

$\frac{s_{car}}{s_{truck}} = \frac{50\ m}{25\ m} \\s_{car} = 2s_{truck}$

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
