Question

A car uses 2*2/5litres of petrol in 1 hours. How many litres of petrol is used by the car in 4*1/3 hours ?
​

Answer 1

Answer:

10 2/5 L

Step-by-step explanation:

Amount of petrol the car uses in 1 hour = 2 2/5 L

Amount of petrol the car will use in 4 1/3 hours = 2 2/5 x 4 1/3 L

                                                                              = 12/5 x 13/3 L

                                                                              = 4/5 x 13/1 L

                                                                              = 52/5 L

                                                                              = 10 2/5 L (answer)

Therefore, the car will use 10 2/5 L in total for 4 1/3 hours.
