If 1l of milk cost 70p find the cost of 100ml and 400ml.

Since 1000ml is 1L, 100 ml is 1/10L.

So 100ml costs 7p 
And 400ml costs 28p.

100ml costs 7p
400ml costs 28p

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.
