Question

Ikkita avtomobil ikki shahardan bir vaqtda bir biri tomon yo'lga chiqdi . Birinchi avtomobil 1 soatda 90 km , ikkinchisi esa 1 soatda 80 km yo'l bosmoqda . Agar ikki shahar orasidagi masofa 1304 km bo'lsa , 2 soatdan keyin ular orasida necha kilometr masofa qoladi ?The two cars drove from the two cities towards each other at the same time. The first car travels 90 km per hour and the second 80 km per hour. If the distance between the two cities is 1304 km, how many kilometers will be left between them after 2 hours?

Answer 1

Determine the distance covered by the first car in 2 hours.

`\begin{gathered} d_1=90\cdot2 \\ =180 \end{gathered}`

Determine the distance covered by second car in 2 hours.

`\begin{gathered} d_2=80\cdot2 \\ =160 \end{gathered}`

Determine the total distance covered by both cars in 2 hours.

`\begin{gathered} d=d_1+d_2 \\ =180+160 \\ =340 \end{gathered}`

The distance left between them after two hours is difference of 1304 and 340. So left distance between them is,

`\begin{gathered} D=1304-340 \\ =964 \end{gathered}`

Thus 964 km left between them after 2 hours.
