Question

A car moves in a straight line at a speed of 52.6 km/h.

How long (in seconds) will it take the car to move 0.48 km at this speed?

Answer 1

32.85 sec.

Step-by-step explanation:

for the car to travel 0.48km it takes 0.48/52.6 hr. because you see if the car were to move 52.6km in one hr you can write it as 52.6/52.6 hrs or rather 1hr.

we know it takes
`(0.48)/(52.6)` hr to travel 0.48km. this is in hours. if we want to convert hours into seconds, we should multiply by 60. and again by 60.

if we multiply by 60 we get the time in minutes( 60 min is 1 hr) and if you multiply that with 60 again we get the answer in seconds.

(0.48/52.6) x 60 x 60 = 32.85 seconds.
