Question

Determine the time taken when distance is 7150km and speed is 780km /hr

Answer 1

Explanation:

Given: Time = ?

          Speed = 780 km/hr

         Distance Travelled = 7150 km

Method : Speed = Distance/time

              Time = Distance/speed

                        = 7150/780

                        = 9.16 hr

We need to convert this into seconds as the unit of time is secs.

So,

= (9.16 * 60)60

= 549.6 * 60

= 32,976 secs

∴the amt of time taken to travel a distance of 7150 km under the speed of 780 km/hr is 32,976 secs.

Hope it Helps.

have a good day.

Answer 2

first you should know know the method for finding time when given distance and speed and the method is D divided by S where D the distance and S the speed

so that is the method

So u say

7150km divided by 780km/hr and the kms cancel out and you remain with hr

so answer is 55over6 or9.1667hrs or 9whole number 1over6.
