Question

Yesterday, Hans went on a bike ride. His average speed was 10 miles per hour. Today, he went on another ride, this time averaging 12 miles per hour. In the two days, he biked for a combined total time of 13 hours

Let X be the number of hours he biked yesterday. Write an expression for the combined total number of miles he biked in the two days.

Answer 1

To find the combined total number of miles Hans biked in the two days, you can use the expression 10X + 12(13 - X), where X is the number of hours he biked yesterday.

Step-by-step explanation:

To find the combined total number of miles Hans biked in the two days, we need to find the individual distances he biked each day and add them together. Let X be the number of hours he biked yesterday. Since his average speed was 10 miles per hour, he biked a distance of 10X miles yesterday.

Today, he biked for (13 - X) hours at an average speed of 12 miles per hour, so he biked a distance of 12(13 - X) miles today. Adding these distances together gives us the expression for the combined total number of miles he biked: 10X + 12(13 - X).

Answer 2

Therefore ,total number of miles he biked in the two days=10x+12(13-x).

Step-by-step explanation:

Given :

Yesterday ,Hans ride bike =10 miles per hour.

Let X be the total number of hour he biked yesterday

Today he ride bike =12 miles per hour.

In two days total he biked =13 hour.

Explanation:

Total number of miles he ride yesterday= 10x

Today he bike ride =(13-X) hour

Total number of miles he ride today=12(13-x)

Therefore ,total number of miles he biked in the two days=10x+12(13-x).
