Question

After driving 152 ​km, 4/5 of a trip is completed. How long is the total​ trip? How many more kilometers must be driven to complete the​ trip?

Answer 1

Answer:

1. Total Trip Distance = 190 kilometers

2. To complete the trip, 38 more kilometers left

Step-by-step explanation:

1.

Let total trip be x kilometers.

So we can say

"152 is $\frac{4}{5}$ of total" --- this into equation is:

$152=\frac{4}{5}x\\x=\frac{152}{\frac{4}{5}}\\x=190$

Total trip is 190 km.

2.

Since already driven 152, to complete 190, you have to drive  $190-152=38$ kilometers more.

So, 38 more kilometers to complete the trip.

Answer 2

Answer:

The trip is 190 kilometers long and 38 more kilometers must be driven to complete the trip.

Step-by-step explanation:

We are given that after driving 152 ​km, 4/5 of a trip is completed and we are to find how long is the total trip and find out how many more kilometers must be driven to complete the​ trip.

Assuming x to be the total kilometer of the trip:

Total kilometers of the trip = $\frac{4}{5}$ × $x=152$

$x=\frac{152*5}{4} =$ 190 kilometers

So, 190 - 152 = 38 more kilometers must be driven to complete the​ trip.
