Answer:
Consider the provided information.
John started a journey from his house to 7:30 in the morning to do to the next town to meet .he drove his car speed of 40km/h and reached town at 10 o clock
That means John 2 and half hour to complete the journey.
Distance=Speed\times TimeDistance=Speed×Time
Substitute the respective values in the above formula.
Distance=40\times 2.50Distance=40×2.50
Distance=100Distance=100
Hence, the distance is 100 km.
Now if we want he reach town at 9:30 that means the he should complete his journey within 2 hrs.
Substitute the value of t=2hr in the above formula.
\begin{gathered}100=Speed\times2\\\\Speed=\frac{100}{2}\\\\Speed=50\end{gathered}
100=Speed×2
Speed=
2
100
Speed=50
Hence, the speed should be 50 km/h.
