Distance-Time Problem: Calculate Car Travel from 200km in 4 Hours to 7 Hours

Question

A car travels a distance of 200 km in 4 hours.
What distance will it travel in 7 hours?

Step-by-Step Solution

To solve this problem, we'll follow these steps:

  • Step 1: Identify the speed of the car using the formula.
  • Step 2: Calculate the distance for 7 hours using the speed.

Now, let's work through each step:
Step 1: Calculate the speed of the car. The speed is calculated by the formula:

Speed=DistanceTime=200 km4 hours=50 km/h \text{Speed} = \frac{\text{Distance}}{\text{Time}} = \frac{200 \text{ km}}{4 \text{ hours}} = 50 \text{ km/h}

Step 2: Use the speed to find the distance traveled in 7 hours. The distance is given by:

Distance=Speed×Time=50 km/h×7 hours=350 km \text{Distance} = \text{Speed} \times \text{Time} = 50 \text{ km/h} \times 7 \text{ hours} = 350 \text{ km}

Therefore, the car will cover a distance of 350 km in 7 hours.

Answer

350
