Answer 1

Answer:

speed = 72 3/4 km/hr

time = 3 1/2 hours.

distance = ?

speed = distance / time

therefore,

distance = speed × time

= 72 3/4 × 3 1/2

72 3/4 = {(72×4)+3}/4

= 291/4

3 1/2

= {(3×2)+1}/2

= 7/2

291/4 × 7/2

= (291×7)/(2×4)

= 2037/8

converting into mixed fraction.

= 254 5/8 (answer)
