Question

The length of a route is 75 km 25 cm. Length of second route is one-fifth of the first route. The length of second route is

• A. 10 km 5 m
• B. 14 km 5 m
• C. 13 km 5 m
• D. 15 km 5 m

Answer 1

The correct option is D 15 km 5 m

Length of the first route
= 75 km 25 m
= 75 × 1000 m +25 m
= 75000 m + 25 m
= 75025 m
Length of the second route
= 75025 m ÷ 5 = 15005 m
= 15000 m + 5 m
= 15 km 5 m
