Answer:

80 km.

Step-by-step explanation:

Given that a car travels 60 km in 45 minutes.

In one minute it travels $\frac{60}{45}$ km

⇒ Hence it travels 1.33 km per minute

In an hour we have sixty minutes. ∴ Distance traveled in 60 minutes is

⇒ 60 × 1.3333 km

⇒ 80 km

∴ Distance traveled by the car in one hour is 80 km

in 1 min --- 60/45

in 60 min -- 60/45 ×60
