Answer 1

Explanation:

Hii There!!!

Given, distance travelled = 72km =) 72000m

Time taken = 4hrs=). 240min =) 14400s

Since, Speed= distance travelled/time taken

                     =72000m/14400s

                     =5m/s

Hope it helps

Answer 2

$\huge\bold{\mathbb{\purple{☆A{\pink{N{\green{S{\blue{W{\red{E{\orange{R☆}}}}}}}}}}}}}$

$Distance, S=72 km$

$Time, t=4 hr$

$Speed = \frac{72}{4} km/hr$

$= \frac{72}{4} \: \times \: \frac{5}{18}$

$=5 m/s$
