Rico bicycles at an average speed of 15.5 miles per hour. What distance will Rico bicycle in 180 minutes?

Tpy6a [65]

Answer:

46.5 miles

Step-by-step explanation:

Average speed × Time in hours = Distance

Average speed = 15.5 Miles per hour

Time = 180 minutes

We convert to hours

60 minutes = 1 hour

180 minutes = x

Cross Multiply

60x = 180

x = 180/60

x = 3 hours

Distance = 15.5 miles per hour × 3 hours

Distance = 46.5 miles

The distance Rico will ride his bicycle is 46.5 miles

Find<br>a,b<br>such<br>that 7.2, a, b, 3 are in A.P.

leonid [27]

Answer:

The value of a = 5.8

The value of b = 4.4

Step-by-step explanation:

Given

7.2, a, b, 3 are in A.P

$2a = 7.2+b$

$b = 2a - 7.2$

a, b, 3 are also in A.P

$2b\:=\:a\:+\:3$

Putting $b = 2a - 7.2$

$2\left(2a-7.2\right)=a+3$

$4a-14.4=a+3$

$\mathrm{Add\:}14.4\mathrm{\:to\:both\:sides}$

$4a-14.4+14.4=a+3+14.4$

$4a=a+17.4$

$4a-a=a+17.4-a$

$3a=17.4$

$\mathrm{Divide\:both\:sides\:by\:}3$

$\frac{3a}{3}=\frac{17.4}{3}$

$a=5.8$

Now, plugging $a=5.8$ in $b = 2a - 7.2$

$b=2\left(5.8\right)-7.2$

$b=2\cdot \:5.8-7.2$

$b=11.6-7.2$

$b=4.4$

Therefore,

The value of a = 5.8

The value of b = 4.4
