Shannon has already cycled 9 kilometers this year, plus she plans to cycle 1 kilometer during each trip to work. How many trips

Oduvanchick [21]

Answer:

Shannon has to make 41 trips to cycle a total of 50 kilometers.

Step-by-step explanation:

Given that

Shannon has cycled 9 kilometers this year

Let x be the number of trips that Shannon will make during the year

As she cycles 1km per trip, the total distance in trips will be: 1x

She has to cycle 50 kilometers in a year so the equation for this problem is:

$9+x = 50$

Solving this equation will give us the number of trips she has to make

$9+x = 50\\x = 50-9\\x = 41$

Hence,

Shannon has to make 41 trips to cycle a total of 50 kilometers.
