Ella and jade both ran a marathone ella finished 4 hours 6 mins and 13 seconds jade finished in 4 hours and 3 mins and 18 second
spin [16.1K]

Answer:

Jade is faster than Ella by 2 minutes and 55 seconds.

Step-by-step explanation:

We are told that Ella and Jade both ran a marathon. Ella finished marathon in 4 hours 6 mins and 13 seconds. Jade finished marathon in 4 hours and 3 mins and 18 seconds.

We can write 4 hour 6 minutes 13 seconds as 4 hour 5 minutes 73 seconds. 1 minute has been borrowed to the seconds side, and seconds become 13+60 = 73 seconds.

We can see that Ella took more time than Jade. Let us find how much more time Ella took than Jade by subtracting time taken by Jade from time taken by Ella.  

4\text{ hr }5\text{ min }73\text{ sec }-4\text{ hr }3\text{ min }18{ sec }= 2\text{ min }55\text{ sec }  

We can see that Jade took 2 minute and 55 seconds less than Ella , therefore, Jade was faster than Ella by 2 minutes 55 seconds.

If a car travels 792 feet in 12 seconds what is the speed of the car in miles per hour?
UkoKoshka [18]

Answer:

Step-by-step explanation:

1 mile contains 5280 feet

x mile contains 792 feet             Cross Multiply

5280 x = 792                               Divide by 5280

x = 792 / 5280

x = 0.15 miles

1 hour = 3600 seconds

Distance travelled in 12 sec = 0.15 miles

                                 3600 sec = x                       Cross Multiply

12x = 3600  * 0.15                                                  Combine

12x =  540                                                               Divide both sides by 12

12x/12 = 540/12

x = 45 miles / hour

A rectangular parking lot has a perimeter of 310 meters. The length is 5 meters more than 4 times the width. What’s is the lengt
max2010maxim [7]

Answer:

w=30  l=125

Step-by-step explanation:

Perimeter =2l+2w

p=310

w =width

4w+5 = length(4 times plus 5 the width)

2(4w+5) + 2w = 310

8w+10 = 2w =310

10w=300

w=30    

30*4=120    120+5=125    l=125

2(125)+ 2(30)=  250+60 =310
