Question 627445
The distance that Cyril drove is
{{{ d[1] = 60*(10/60) }}} km ( I changed minutes to hours )
The distance that Josh drove is
{{{ d[2] = 90*(5/60) }}} km
{{{ d[1] + d[2] = 60*(10/60) + 90*(5/60) }}}
{{{ d[1] + d[2] = 10 + 7.5 }}}
{{{ d[1] + d[2] = 17.5 }}} 
The distance to Josh's office from Cyril's house
is 17.5 km
