Answer 1

Step-by-step explanation:

First change all the values to improper fraction.

In these type of questions use the given below formula to save our time.

S1/S2=√(T1/T2)

where S1, S2 and T1, T2 are the respective speeds and times of the objects.

45/S2=√(10/3)/(24/5)

S2=45×6/5

= 54 km/hr

∴Required speed = 54km/hr

Hope this helps
