A car travels a distance of 200 km in 4 hours.
What distance will it travel in 7 hours?
To solve this problem, we'll follow these steps:
Now, let's work through each step:
Step 1: Calculate the speed of the car. The speed is calculated by the formula:
Step 2: Use the speed to find the distance traveled in 7 hours. The distance is given by:
Therefore, the car will cover a distance of 350 km in 7 hours.
350
What is the ratio between the orange and gray parts in the drawing?
Distance isn't additive like that! You need to think about rate of travel. The car covers a certain distance per hour, so more hours means proportionally more distance covered.
This problem assumes constant speed (uniform motion). In real life, cars speed up and slow down, but math problems usually assume steady speed unless stated otherwise.
Think D = S × T (Distance = Speed × Time). You can rearrange this:
Yes! You can write: . Cross-multiply to get the same answer: 350 km.
Always include units in your answer! Since the question asks for distance, your answer should be in kilometers (km), just like the given information.
