Explanation:
Speed of the marathon runner, v = 9.51 mi/hr
Distance covered by the runner, d = 26.220 mile
Let t is the time taken by the marathon runner. We know that the speed of the runner is given by total distance divided by total time taken. Mathematically, it is given by :
t = 2.75 hours
Since, 1 hour = 60 minutes
t = 165 minutes
Since, 1 minute = 60 seconds
t = 9900 seconds
Hence, this is the required solution.
Answer:
3.75 hours
Explanation:
By
where v is the velocity (or speed in this case)
d is the distance travelled
t is the time taken
Therefore it takes 3.75 hours for the bus to travel 150 km and 40 km/hr.
