Given,
Toy car moves 4 cm forward and 3 cm backward in 1 minute
To Find,
Time taken by the toy car to cover 40cm =?
Solution,
Distance travelled in 1 minute = (+4cm) forward and (-3cm) backward
Distance travelled in 1 minute = 4 - 3
Distance travelled in 1 minute = 1 cm
Toy car travels 1 cm in 1 minute then it will travel 40 cm in
Time taken by the toy car to cover 40cm = (1/1)* 40
Time taken by the toy car to cover 40cm = 40 minutes
Hence, the toy car will take 40 minutes to cover 40 cm
