Using the relation between velocity, distance and time, it is found that he traveled 281.25 km by bus and 1618.75 km by plane.

<h3>What is the relation between velocity, distance and time?</h3>

Velocity is distance divided by time, that is:

v = \frac{d}{t}

In this problem, first he traveled a distance of d km by bus, with an average speed of 60 km/h and a time of t, hence:

60 = \frac{d}{t}

d = 60t

Then, by plane, he traveled a distance of 1900 - d km, with an average speed of 700 km/h and a time of 7 - t, hence:

700 = \frac{1900 - d}{7 - t}

Since d = 60t, we have that:

700 = \frac{1900 - 60t}{7 - t}

1900 - 60t = 4900 - 700t

640t = 3000

t = \frac{3000}{640}

t = 4.6875

Hence:

d = 60t = 60 x 4.6875 = 281.25 km

1900 - d = 1900 - 281.25 = 1618.75 km

He traveled 281.25 km by bus and 1618.75 km by plane.

Divide 30 in the ratio of 2 : 4
cricket20 [7]
60 because 2:4 is 1/2, and when you divide by a fraction, you multiply by the reciprocal (2/1 instead of 1/2) which would be 60 in this case.

while swimming a 2km race, Adam changes from breaststroke to butterfly every 200m. How many times does he switch strokes during
aleksley [76]

in the first half he would have swam 1 km. there are 1000m in a km so 1000/200=5 so he swam the first 200 fly, then a 200 breast, then a 200 fly again, then another 200 breast the finish the first 1 km with a 200 fly. so we switched strokes 4 times.





PS i wouldn't recommend doing a 2 km swim fly and breast
