Hi,

1. Time taken by Ricky to finish her homework = 5/12 hours = 25 Minutes.

Time taken by Bob to finish his homework = 4/3 hours = 1 Hour, 20 Minutes

• Bob took more time to complete his homework

2. Some rational numbers between -3/13 and 9/13

-2/13, 8/13, 2/13, -1/13, 7/13, 1/13 etc.

3. Distance travelled by the car towardsEast = 5 1/2 Killometers = 11/2 Killometers

Distance travelled by the car towardsWest = 7 15/22 Killometers= 169/22 Killometers

The place where the car is situated = 11/2 KM* -169/22KM* = 121/22 KM* +169/22 KM* = 290/22 KM*

NOTE:- KM* = Killometers

4. It may take him 20 to 25 minutes
