Question

A car is moving at the speed of 40 2/3 km/hr. Find how much distance will it cover in 9/10 hours ?

Answer 1

Answer:

here's your answer, grab it

Step-by-step explanation:

GIVEN -

speed of the car - 40 2/3 km/hr

time - 9/10 hrs

now convert the speed to improper fraction -

40 2/3 km /hr = 122/3 km/hr

now convert the time to minutes -

$60 \times 9 \div 10 = 54 minutes$

(as the time is in minutes, we will have to convert the speed to m/min)

formula-

speed = distance/ time

${122 \times 1000}\div 60 \times 3 = distance \div 54$

$670 \times 54 = distance$

[tex]distance = 36180 metre / minutes
