Question

A fighter plane can cover 490km in 1¾ hours. How much distance will it cover in 4³/7 hours

Answer 1

1240 km.

Step-by-step explanation:

Distance= 490 km

Time=1¾ hours or 7/4 hours

Speed= Distance/Time

= 490 ÷ 7/4

= 490 × 4/7

= 70 × 4

= 280 km/h

Time= 4³/7 or 31/7

Speed= 280 km/h

Distance= Time×Speed

= 31/7 × 280

= 31 × 40

= 1240 km
