Answer:A) 1.5

Step-by-step explanation: Bob runs at the rate of 8mins per mile

In 60mins his rate would be=60/8=7.5

Let a be the distance he further runs south

2s+3.25

Total distance covered in 50mins=Time=distance/speed=

50/60

50/60=2s +3.25/7.5

Cross multiply

60(2s+3.25)=50×7.5

120s+195=375

120s=375-195

S=180/120

S=1.5

umka21 [38]

Answer:

The speed of cyclist is <u>0.1 mile per minute</u>.

And the cyclist will trek <u>1 mile</u> in 10 minutes.

Step-by-step explanation:

Given:

A cyclist rides his bike at a speed of 6 miles per hour.

Now, to get the speed of cyclist in miles per minute. And miles the cyclist trek in 10 minutes.

As, 1 hour = 60 minutes.

Now, to solve by using unitary method:

If, in 60 minutes cyclist rides 6 miles.

Then, in 1 minute cyclist rides = $\frac{6}{60}=0.1\ mile.$

So, in 10 minutes the cyclist trek = $0.1 \times 10=1\ mile.$

Therefore, the speed is 0.1 mile per minute.

And the cyclist will trek 1 mile in 10 minutes.

Answer: 5-2x=6-x, x= -1/3

Explanation:

“When I double it and subtract it from five it is the same as subtracting it from six”

So double means multiply by two, and the same as means equal. Use a variable to represent the number.

Therefore your equation is:
5-2x=6-x

So solving the equation would be:
-2x-x = 6-5
-3x = 1
x= -1/3
