Speed 45m/s
Distance = speed × time
d = 45 × t
d= 45t
So, this is your equation for distance travelled in h time.
Answer:
2220
Step-by-step explanation:
gcd of all numbers
3,4,7,5,6,8
2 = 3,2,7,5,3,4
2 = 3,1,7,6,3,2
2 = 3,1,7,5,3,1
3 = 1,1,7,5,1,1
Answer:

Step-by-step explanation:

Make denominators same:

Add the numerators:


Apply the rule:

Therefore,

Cancel out common factor of 2x+1:

You 2l x 2w and blah blah blah blah blah blah blah blah
Rate is given by:
rate=(distance )/(time)
Martin's rate will be:
(3 1/3)/(1/6)
=(10/3)/(1/6)
=20 meters per hour
Alexia's rate is:
(17 1/2)/(5/6)
=(35/2)/(5/6)
=21 meters per hour
